The ATR 42-500 offers
a combination of high overall performance and comfort unmatched in its
class, while keeping the competitive cost-efficiency, which are the
brand image of ATR aircraft.

The ATR 42-500 secondary structure is extensively made of corrosion-resistant composite material.
Generous operational weights adapted to new regulatory standards
provide the ATR 42-500 with a maximum range of 840 Nm or an out and
return trip of 370 Nm without refueling, both at full passenger payload.
Short and narrow runways, hot and high airports, demanding airfields
are the daily environment for ATR 42-500 worldwide. From Latin America
to Asia-Pacific region, everywhere in Europe and in tough Middle East
and African climates, ATR 42-500 provides unrivalled flexibility and
reliability, generating revenues and profitability for regional
airlines.

The ATR 42-500 provides passengers with an on-board comfort and services comparable to the jetliner

High cruise ceiling of about 7,000 m (21,000 ft) with inherent stability

Large overhead bins including a handrail to facilitate passengers and crew movement along the cabin

Optimized view (more windows than rows of seats)

Individual reading lights and cabin attendant call system

A quiet, comfortable and spacious cabin with a new design list item

The ATR 42-500 cabin layout benefits from the improvements in noise and
vibration:

Attachment of the panels and overhead bins to the structure by specially
designed dampers, avoiding vibration transmission from the structure to the
interior furnishings

Cabin partitions treated to reduce reverberation phenomena in the forward
and rear cabin area

New insulation blankets with an optimized thickness and made of
waterproof material

Stiffening of frames located in the propeller area

Installation of Dynamic Vibration Absorbers on the upper side of the
frames and on the floor beams, greatly reducing the transmission of noise
generated by the propeller blades

Skin damping treatment through viscomaterial strips on the panels,
reducing noise propagation by the skin

The new 568F six-blade Hamilton Standard propeller is specially
optimized for low cabin noise in climb and cruise and low
vibration.
It features:

New Propeller Electronic Control

New Propeller Valve Module, ensuring very accurate propeller speed and
phase control

Optimum synchrophasing between the two propellers, resulting in optimum
comfort even in turbulence

ATR has always made
optimal use of advanced technologies providing fuel-efficient aircraft
to the airline industry. ATR aims at furthering its contribution to
ensure a sustainable future for the aviation industry, and reconciling
air transport growth while minimizing environmental impact.

Highly efficient and operating at lower speeds, ATR aircraft
contribute to a small fraction of aircraft attributable emissions. They
operate at low altitudes, have no effect on the ozone layer and upper
atmosphere, and provide optimized capacity, to adapt frequencies to the
regional airlines requirements.
Material, procedures and technologies used to produce ATR aircraft
are constantly improved and monitored to minimize environmental impact
across the entire life cycle:

Reducing waste production at source and increasing waste recycling rates

The latest propulsion technology combined with optimally designed
high-lift systems make ATR -500 New Generation aircraft quiet
neighboors. They meet ICAO noise requirements with wide margins, and
hence keeping the environmental impact to a minimum.
The ATR 42-500 is more efficient than regional jet aircraft on
short-haul routes: it emits about 20% less CO2 per passenger-km than
new-generation jets and up to three times less CO2 than older ones.

The ATR 42-500 has the lowest seat-mile costs in its market segment.
On 300 Nm sector, the ATR 42-500 features less fuel consumption,
lower engine maintenance costs and significantly lower airport charges,
when compared to 50-seater jet.
The ATR 42-500 has the advantage of a proven design and a high degree of
commonality with other models to minimize training and maintenance
costs and ensure enhanced cost-efficiency for more profitability.
